Daniel Bolt
Professor
| Dr. Bolt joined the Department of
Educational Psychology in the spring of
1999, coming from the Laboratory for
Educational and Psychological Measurement
at the University of Illinois. In addition to his
own research, he collaborates on various
projects related to the development and
statistical analysis of educational and
psychological tests. Dr. Bolt teaches courses
in test theory, factor analysis, and
hierarchical linear
modeling.
Research
Statement:
"My interests are
in the theory and application of psychometric
methods in education and psychology. I am
especially interested in the application of
latent variable models for purposes of test
validation, assessment of individual
differences (such as response styles), and
cognitive diagnosis.
Most of my research is in item response
theory (IRT), including its application to
issues such as differential item functioning
and test dimensionality assessment. I am
also interested in the development of
nonparametric IRT methods, which relax
certain modeling assumptions and have the
potential to increase the flexibility and
efficiency of IRT in many testing
applications."
